‘Angry Birds’ Spreads Wings

“Angry Birds” is flapping from touch screens to big screens, books and toys, testing whether one of the best-known mobile apps can become an entertainment franchise akin to Mickey Mouse and Iron Man.

Finland’s Rovio Entertainment Ltd., the game’s developer, this month will publish the first in a line of books, “Bad Piggies Egg Recipes,” with such fare as egg-salad sandwiches and egg sushi. The title refers to the game’s porcine thieves, who become targets for an enraged group of birds after stealing their eggs.
